[0035] The target torque can be the maximum torque of the target vehicle in the normal driving state.

[0036] In an optional embodiment, the target liquid level of the target oil can be determined by comparing the target state parameter and the preset state parameter, wherein the target liquid level can be the liquid level of the target oil when no abnormality occurs, which is estimated according to the target state parameter and the preset state parameter. The preset state parameter can be the maximum parameter in the normal driving state of the vehicle and can be set by itself.

The target transmission can continuously calculate during operation and identify the current liquid level in real time. When the current liquid level is lower than the target liquid level, the liquid level detection program will be triggered.

[0038] In step S106, the target oil is detected based on the current speed and the target speed of the target motor, and a detection result is obtained, wherein the detection result is used to indicate whether the target oil in the target transmission is abnormal.

[0039] In an alternative embodiment, after the target speed is determined, the target speed can be compared with the current speed, and it is determined whether the current speed is greater than the target speed. If the current speed is greater than the target speed, it is determined that the target oil in the target transmission is abnormal.

[0040] In another alternative embodiment, when the detection result is that the target oil in the target transmission is abnormal, a prompt message can be sent to prompt the user that the target oil is abnormal and needs to be detected manually.

[0050] The torque control mode can be one of the working modes of the target motor. In the torque control mode, the motor can output torque information.

[0051] The target curve diagram can be used to represent the relationship between the target torque and the target speed. Optionally, the target speed corresponding to the target torque can be determined according to the target curve diagram.

[0052] In an optional embodiment, after the system issues the target detection task, the working state of the target motor can be set to the torque control mode according to the detection task.

When the motor is in the torque control mode, the target curve diagram can be obtained, and the motor speed information can be further obtained based on the target curve diagram.

[0053] In another optional embodiment, after receiving the target detection task, the controller can control the target motor to enter the torque control mode in the background in the target driving cycle, set the target torque of the target motor, obtain the target speed of the motor under the target torque based on the oil temperature and the motor external characteristic information, and monitor the current speed of the target motor at the same time. The target speed and the current speed are compared, and if the current speed is greater than the target speed, it indicates that the actual load of the target motor is lower than the load under the normal state, that is, the target motor also inhales air while inhaling oil, and that the oil appears to be leaking.

[0054] Optionally, the target oil is detected based on the current speed and the target speed of the target motor to obtain a detection result, including: determining whether the current speed is greater than the target speed; and in the case where the current speed is greater than the target speed, determining that the target oil in the target transmission appears to be abnormal.

[0055] In an optional embodiment, whether the oil appears to be abnormal can be fed back through the feature of the load mutation of the motor. If the oil leaks, the motor will inhale air, and the load of the motor when rotating will become smaller. At this time, the speed of the motor will become larger, and if the speed is greater than the maximum speed under the normal driving state of the vehicle, it can be determined that the oil leaks.

[0056] Optionally, in the case where the detection result shows that the target oil in the target transmission appears to be abnormal, prompt information is output, wherein the prompt information is used to prompt that the target oil in the target transmission appears to be abnormal.
